Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a binding tool fixing structure, and more particularly, to a binding tool fixing structure capable of easily separating a binding tool fixed to a cover body.
[0002]
[Prior art]
Conventionally, a binder or a file including a binding tool on the inner surface side of a back cover or a back cover is commercially available. As a binding tool used for this binder, for example, a base and a binding member disposed on the base are provided.
[0003]
When fixing the base to the spine, a configuration is generally adopted in which a plurality of holes are formed at the coaxial line position between the base and the spine and fixed with rivets through the holes. Yes.
[0004]
[Problems to be solved by the invention]
However, the cover side of the binder is formed of hard paper or a resin sheet, while the binding side is often made of metal to maintain load bearing performance. It is required to do. However, in the rivet fixing method, it is difficult to separate the two, and the fact is that both are discarded without being separated.
[0005]
In addition, although segregated disposal has recently been strongly requested from the viewpoint of protecting the recent garbage disposal problem or the natural environment, it is more preferable to fundamentally prevent the generation of garbage. In this respect, the binding tool used for the binder is rarely unusable by itself, and it is general that only the cover side becomes obsolete and cannot be used.
[0006]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such a problem. The purpose of the present invention is to make it possible to separate the binding tool and the cover body easily and to separate and discard them without difficulty. An object of the present invention is to provide a fixing structure for a binding tool that can be reused.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a binding device fixing structure for fixing a base having a binding member to a predetermined cover body.
A leg tube fixed to the base and disposed through a hole formed in the cover body, and inserted into the leg tube from the outer surface side of the cover body, and with respect to the leg tube And a detachable shaft member,
The leg tube includes a main body cylinder portion that penetrates the hole, a flange portion that is connected to one end side of the main body cylinder portion, and is attached to the outer surface side of the cover sheet, and the flange portion and the main body cylinder portion. With a deformation allowance formed by
When the shaft member is inserted into the leg tube after being inserted into the hole while reducing the diameter of the flange portion, the main body cylinder portion expands radially outward so that the main body cylinder portion becomes the inner peripheral surface of the hole. The structure of applying a pressure contact force to is adopted. According to such a configuration, as long as the shaft member is kept inserted through the leg tube, the fixed state of the binding tool is stable. On the other hand, by pulling out the shaft member from the leg tube, it is possible to separate the binding tool and the cover body without difficulty, not only facilitating separation and disposal, but even if the cover body becomes obsolete and cannot be used. By replacing only the new cover body, it is possible to reuse the product until the end of its product life without discarding the binding tool.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The deformation allowance in the present invention may be constituted by a notch portion extending from the flange portion to the main body cylinder portion. As a result, the main body cylinder portion of the leg cylinder can be easily expanded and deformed radially outward simply by inserting the shaft member into the leg cylinder, and the aforementioned pressure contact force can be reliably exerted on the inner periphery of the hole. . At this time, it is preferable that the notch portions are formed at symmetrical positions with an interval of about 180 degrees. In this way, the expansion deformation can be easily extended to the entire outer periphery of the main body cylinder portion, that is, damage that makes it impossible to reuse the leg cylinder without causing partial deformation. Can also be prevented.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0010]
FIG. 1 shows a schematic perspective view in which a binding device fixing structure according to the present invention is applied to a binder, and FIGS. 2 and 3 show a side view and a side sectional view of a main part thereof. In these drawings, the binder 10 includes a cover body 11, a binding tool 12 located on the inner surface side of the cover body 11, and a fixing tool 13 that fixes the binding tool 12 to the cover body 11 at two positions. Has been. In the present embodiment, the cover body 11 is constituted by a vertically elongated spine cover 15 which is a fixed surface of the binding tool 12, and a front cover 16 and a back cover 17 which are continuously provided on both left and right sides of the spine cover 15. . Here, holes 15A (see FIG. 3) for mounting the fixture 13 are provided at two positions in the longitudinal direction (vertical direction) of the spine cover 15.
[0011]
The binding tool 12 is provided at a base 20 extending along the vertical direction of the spine 15, a large number of rings 21 as binding members provided on the base 20 at predetermined intervals, and provided at both longitudinal ends of the base 20. The operation piece 22 is provided. The ring 21 is a conventional type that forms a closed loop in a state of being abutted at the upper center thereof, and the operation piece 22 is tilted outward to open the upper center of the ring 21 so as to add and remove documents. Can be done.
[0012]
A hole 25 is provided at two positions in the longitudinal direction of the base 20, and the fixture 13 is disposed at the position of the hole 25. The fixture 13 includes a leg tube 26 fixed to the base 20 and a shaft member 27 that passes through the hole 15 </ b> A of the spine cover 15 and is inserted into the leg tube 26.
[0013]
The leg tube 26 is provided on a hollow main body cylinder portion 30 having a female screw portion 29 for screwing the shaft member 27 on the inner peripheral surface thereof, and on the upper end side of the main body cylinder portion 30 in FIG. The base portion 20 includes a connecting portion 31 that is caulked in a region where the hole 25 is formed, and a flange portion 32 that is connected to the outside from the lower end of the main body cylinder portion 30 and attached to the outer surface of the spine cover 15. . Further, as shown in FIG. 4, the leg tube 26 has a notch 33 as a split slit-shaped deformation margin extending from a 180 degree relative position of the flange portion 32 toward a position upward in the axial direction of the main body tube portion 30. Is formed. The notch 33 has a shape in which the lower part has a slit width larger than the upper part, so that when the picking force is applied to the leg tube 26 so as to be sandwiched from both the left and right sides in FIG. Even when the binding tool 12 is mounted with the leg tube 26 fixed to the base 20 in advance, the flange portion 32 passes through the hole 15A of the spine cover 15 and is on the outer surface side of the spine cover 15. It can be set at the position to be attached. The outer diameter of the main body cylinder portion 30 in an unloaded state is approximately the same as the inner diameter of the hole 15A, and when the shaft member 27 is inserted, the main body cylinder portion 30 expands in the radial direction and the hole It is set so that the inner peripheral surface of 15A is pressed strongly.
[0014]
The shaft member 27 includes a shaft body 35 having a male thread portion 34 that can be screwed into the body tube portion 30 on the outer peripheral surface, and a flange portion 32 of the leg tube 26 connected to the lower end of the shaft body 35. A flange portion 36 that can be attached to the upper portion and a groove 37 that extends in the radial direction of the flange portion 36 through a substantially central portion of the lower end of the shaft portion main body 35 are configured.
[0015]
Next, how to attach and detach the binding tool in this embodiment will be described. Here, it is assumed that the leg tube 26 is fixed to the base 20 of the binding tool 12 in advance.
[0016]
First, when the binding tool 12 is fixed, the leg tube 26 hung from the base 20 is picked, and the flange portion 32 is reduced in diameter so that the slit width of the notch portion 33 is narrowed. The hole 15A is inserted from the inside. Then, when the insertion is completed, the flange 32 is engaged with the formation edge region of the hole 15 by releasing the finger. Thereafter, the shaft member 27 is inserted into the leg tube 26, and the shaft member 27 is rotated and screwed into the leg tube 26, whereby the slit width of the notch 33 is slightly enlarged, and the main body tube portion 30. The outer peripheral surface of the inner surface presses the inner peripheral surface of the hole 15A. At the same time, the flange portion 32 of the leg tube 26 is strongly sandwiched between the outer surface of the spine 15 by the flange portion 36 of the shaft member 27, thereby completing the fixing operation of the binding tool 12.
[0017]
On the other hand, when removing the binding tool 12, the shaft member 27 is rotated in the opposite direction to the above and is extracted from the leg tube 26, and the leg tube 26 is opened while operating to narrow the slit width of the notch 33 described above. Pull out from 15A.
[0018]
Therefore, according to such an example, the effect that attachment and detachment of the binding tool 12 can be performed very simply and quickly is obtained.
[0019]
Note that the present invention is not limited to the binding tool 12 shown and described, and can be applied to various binding tools having a configuration capable of binding a document. Further, the fixture 13 including the leg tube 26 and the shaft member 27 is not limited. For example, in the above-described embodiment, the configuration in which the leg tube 26 and the shaft member 27 are combined by the screw structure is adopted. However, as shown in FIG. 5, the outer peripheral portion of the main body cylinder portion 30 in the leg tube 26 is depressed inside. In this way, the inner peripheral rib forming recess 40 is formed on the inner peripheral surface so that a rib (not shown) can be formed, while the outer peripheral surface of the shaft body 35 on the shaft member 27 side can be engaged with the rib. It is good also as a structure which the recessed part 41 is provided and the inner peripheral rib formation recessed part 40 and the recessed part 41 are mutually fitted by inserting the shaft member 27 in the leg cylinder 26. FIG. At this time, a central recess 42 is provided on the upper end surface of the shaft body 35, and the shaft member 26 can be dropped from the leg tube 26 by hitting the center recess 42 with the tip of a driver. It is possible. According to such a modified example, the same effect as the above-described embodiment can be obtained practically, and the effect that the shaft member 27 can be attached and detached more easily and quickly can be added.
[0020]
Further, the shape of the notch 33 is not particularly limited as long as a predetermined amount of diameter reduction and expansion deformation of the main body cylinder portion 30 and the flange portion 32 can be expected. The number can also be increased or decreased arbitrarily.
[0021]
【The invention's effect】
As described above, according to the present invention, a deformation allowance is provided across the flange portion and the main body cylinder portion, and when the shaft member is inserted into the leg tube, the main body cylinder portion expands radially outward. Therefore, as long as the shaft member is kept inserted through the leg tube, the fixed state of the binding tool is stabilized. It becomes possible. Further, by pulling out the shaft member from the leg tube, the binding tool and the cover body can be separated without difficulty, and separation and disposal are facilitated.
[0022]
Further, since the deformation allowance is constituted by a notch portion extending from the flange portion to the main body cylinder portion, it is possible to secure a large diameter reduction and expansion deformation amount between the flange portion and the main body cylinder portion. The force can be reliably applied to the inner periphery of the hole. In particular, when the notch portions are formed symmetrically at positions spaced apart by approximately 180 degrees, the expansion deformation can easily extend over the entire outer periphery of the main body cylinder portion, resulting in partial biased deformation. It is possible to prevent the leg tube from being damaged without causing it.
